Persistent Biomechanical Alterations After ACL Reconstruction Are Associated With Early Cartilage Matrix Changes Detected by Quantitative MR. [PDF]

, 2016
BackgroundThe effectiveness of anterior cruciate ligament (ACL) reconstruction in preventing early osteoarthritis is debated. Restoring the original biomechanics may potentially prevent degeneration, but apparent pathomechanisms have yet to be described.

Patients with preoperative bone marrow oedema benefit more substantially from medial meniscus posterior root repair

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To analyze the clinical outcomes of the surgical repair of medial meniscus posterior root tear (MMRT) in patients with preoperative bone marrow oedema (BME). Methods Patients who underwent arthroscopic pull‐out repair for MMRT between 2010 and 2022 were retrospectively reviewed, and those with a minimum of two years of follow‐up were ...

Three-dimensional MRI shows cartilage defect extension with no separation from the meniscus in women in their 70 s with knee osteoarthritis

Scientific Reports, 2022
The positional relationship between cartilage defects and the meniscus is poorly understood for osteoarthritis of the knee. Our purpose was to clarify how cartilage defects extend and their association with the meniscus location during osteoarthritis ...

Postcommercialisation outcomes of bridge‐enhanced anterior cruciate ligament restoration: The first 100 Bridge registry patients

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
ABSTRACT Purpose To review adverse events and outcomes at least 1 year postoperatively from Bridge enhanced ACL restoration (BEAR) in the first 100 subjects of the Bridge registry, a postcommercialisation prospective cohort. Methods Consecutive BEAR patients were invited to enroll in the Bridge registry.

The meniscofemoral ligaments do not contribute to restriction of posterior tibial translation: A robotic biomechanical analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The aim of this study was to quantify the contribution of the meniscofemoral ligaments (MFLs) on restraining a posterior tibial translation (PTT) in the human knee joint. Methods Sixteen human cadaveric knee joints were tested in a robotic test setup with six degrees of freedom.

Posterior Tibial Slope Is Not Correlated With Meniscal Tears in Anterior Cruciate Ligament Reconstruction

Arthroscopy, Sports Medicine, and Rehabilitation
Purpose: To evaluate the impact of the tibial slope on the severity and location of meniscal tears in patients presenting with anterior cruciate ligament (ACL) rupture. Methods: We conducted a single-center retrospective observational study.

Early degeneration of the meniscus revealed by microbiomechanical alteration in a rabbit anterior cruciate ligament transection model

Journal of Orthopaedic Translation, 2020
Background: The microbiomechanical properties of the meniscus influence the cell response to the surrounding biomechanical environment ​and are beneficial to understand meniscus repairing and healing. To date, however, this information remains ambiguous.
